Personal statement

Charles MacLeod is a Professor in the Centre for Ultrasonic Engineering. 

He is the Babcock International Group / Royal Academy of Engineering Chair in Sensor-Driven Automated Welding.

He is director of the Sensor Enabled Automation & Robotics Control Hub (SEARCH), a £24M research innovation and technology transfer laboratory. Aligned to this, he is Course Director of the Autonomous Robotic Intelligent Systems (ARIS) MSc.

His research is primarily associated with the inspection and manufacturing enhancement of high-value assets and components, where he leads a number of high-profile inter-disciplinary in-process welding and metal additive research projects.

He has driven and co-developed core robotic and ultrasonic technology from fundamental EPSRC research, which is now being licensed by a leading industrial organisation and co-developed an innovative inspection robot for a critical life-extension inspection at Sellafield Reprocessing Facility.

He is the PI and designer of the Engaging Robotic Interactive Cell (ERIC) STEM Outreach cell. 

His research interests include:

Non-Destructive Evaluation

In-Process Inspection of Fusion Welding & Metal Additive Components

Sensors including Ultrasonic, Electromagnetic, Tactile and Visual

Automation & Robotics 

Automated Manufacturing & Welding

Multi-Modal Sensing for Heavy-Manufacturing Robotic Welding
Loukas, Charalampos (Principal Investigator) MacLeod, Charles Norman (Principal Investigator)
Fusion welding of metals is a joining method fundamental to High-Value Manufacturing (HVM). Distinctive challenges such as the global shortage of welders and the increasing requirement for high-integrity components in the energy and defence sectors fuel the need to research and adopt digital welding
technologies such as sensor-enabled robotic welding. Surface and volumetric sensing approaches at the point of manufacture coupled with real-time robotic motion offer the possibility to control, adapt and consistently ensure defect-free fusion. This project seeks to investigate novel event-based neuromorphic vision sensing coupled to high-temperature in-process ultrasonic imaging to deliver high-integrity welds right the first time.

Residual stress measurement round robin on a wire arc additively manufactured titanium alloy
Javadi, Yashar (Principal Investigator) Sun, Yongle (Co-investigator) Alipooramirabad, Houman (Co-investigator) MacLeod, Charles Norman (Co-investigator) Reid, Mark (Co-investigator)
The aim of this project is the development of a round-robin residual stress measurement to investigate the residual stress in ‎titanium (Ti–6Al–4V) Wire + Arc Additive Manufacture (WAAM) ‎components. Cranfield will contribute with the manufacturing and finite element modelling of the WAAM samples. ‎ANSTO is supporting the project with residual stress measurement using Neutron Diffraction (ND) method‎.
